After some poorer air quality overnight, Saturday gives us a good chance at some decent air quality. After midnight, we saw a quick increase then decrease in PM2.5 levels, and we should see the decrease continue for a few more hours, possibly through the early afternoon. Then for the remainder of the day, we should see a general upward trend for PM2.5, although the increase could be slow enough to keep us out of the Unhealthy range for a good part of the day.
